Foreword
GB/T 11441 "in telecommunication and electronic equipment - transformers and inductors core piece" is divided into two parts.
--- Part 1. mechanical and electrical properties;
--- Part 2. Soft metal laminations lowest permeability specifications.
This section GB/T 11441 Part 1.
This section drafted in accordance with GB/T 1.1-2009 given rules.
This Part replaces GB/T 11441-1989 "telecommunication and electronic equipment transformers and inductors laminations."
This section compared with the GB/T 11441-1989, the main changes are as follows.
--- Increasing the stacked core with the provisions (see Chapter 5);
--- Increasing the stacked core with YS, YSUI1, YSUI2 and stacked laminations YEx4, YEE2-L model (see para.
Chapter 13);
--- Expands the size YEI1 (see Chapter 13);
--- Canceled model YED2, YEE4, YEF4 of stacked laminations (see Chapter 13);
--- Provisions of the stacked core electrical characteristics (see Chapter 14);
--- Increase the mechanical properties of the stacked core (see Chapter 17);
--- Increased YEI1, YUI1, YUI2, YM1 openings (see Chapter 13);
--- Added Appendix A. In Appendix A, we describe the magnetic polarization and magnetic field strength H and J units total apparent power change
Operators relationship, the provisions of the reactive power and active power loss characteristics, related factors and formulas.
This section identical with IEC 60740-1.2005 "communication and electronic equipment laminations for transformers and inductors - Part 1. mechanical and
Electrical properties. "
This part of IEC 60740-1.2005, compared also made the following editorial changes.
--- With "this Part" instead of "this International Standard";
--- Normative references, the guide word press GB/T 1.1-2009 requirements;
--- References in some of the standard replaced by the use of international standards to national standards or industry standards;
--- With a decimal point instead of the IEC standard as decimal point ",". ",";
--- In the calculation formula, the value is multiplied by the multiplication sign "×" dot instead of "*";
--- Remove the IEC standard foreword.
This part is proposed by the Ministry of Industry and Information Technology of the People's Republic of China.
This part of the National Magnetic components and ferrite materials Standardization Technical Committee (SAC/TC89) centralized.
